Not totally sure how I came across this but it probably has something to do with seeking immortality. I used to be a huge fan of Doctor Who back in the day. They used to hold Doctor Who marathons on tv and they would go all day. Some of the movies were classic. Can't remember them now though.
Not something younger people would watch. They just seem very budget now.
Enjoy this clip. I found it pretty cool.
This is where the five doctors meet I think.
